revlog: use bytes() to ensure text from _chunks is a reasonable type

revlog: extract first byte of revlog with a slice so it's portable

revsetlang: slice out single bytes instead of indexing For portability with Python 3.

lock: use %d to format integer into a bytestring

parser: use %d instead of %s for interpolating error position Error position is an int, so we should use %d instead of %s. Fixes failures on Python 3.

manifest: unbreak pure-python manifest parsing on Python 3

context: use portable construction to verify int parsing

ui: portably bytestring-ify url object

scmutil: fix key generation to portably bytestringify integer

branchmap: stringify int in a portable way We actually need a bytes in Python 3, and thanks to our nasty source loader this will portably do the right thing.

branchmap: don't use buffer() on Python 3 This is certainly slower than the Python 2 code, but it works, and we can revisit it later if it's a problem.

py3: use bytearray() instead of array('c', ...) constructions Portable from 2.6-3.6.

summary: don't explicitly str() something we're about to %s str() is wrong on Python 3 here, and %s implicitly calls str() anyway, so this was just extra dancing for no reason.

context: implement both __bytes__ and __str__ for Python 3 They're very similar, for obvious reasons.

context: work around `long` not existing on Python 3 I can't figure out what this branch is even trying to accomplish, and it was introduced in ac89a23ca814 which doesn't really shed any insight into why longs are treated differently from ints.

phases: explicitly evaluate list returned by map On Python 3 map() returns a generator, which bool()s to true even if it had an empty input set. Work around this by using list() on the map() result.

ui: check for --debugger in sys.argv using r-string to avoid bytes on py3 Our source loader was errantly turning this --debugger into a bytes, which was then causing me to still get a pager when I was using the debugger on py3. That made life hard.

minirst: use bytes.strip instead of str.strip bytes.strip exists in Python 2.6 and Python 2.7 also.

smcposix: pass unicode as first argument to array.array This is an instance where we can safely convert the first argument, rest are the cases except one where we are using 'c' which is not there in Python 3. So that needs to be handled differently. This will help in making `hg help` run on Python 3.

util: pass encoding.[encoding|encodingmode] as unicodes We need to pass str to encode() and decode().
